The nature of the fluctuations that are inevitably present in SASE-FEL pulses is shown to play a pivotal role in the success of the decorrelation. Our analysis is performed in connection with specific recent experimental results from FLASH in the soft x-ray regime.</p> figure;fel;molecule;framework;interaction;phase;abstract;analysis;dynamic;nature;role;fluctuation;flash;pulse;bandwidth;regime;decorrelated;decorrelation;experiment;model;Atomic Physics;Molecular Physics 2013-08-13
